The name of (Ban)wolseong thanks to its having a shape like a half-moon. Wolseong fortress is one of 'Gyeongju Historic Area', world heritage. The Silla kingdom's royal palace previously maintained its capital fortress at the locale of Wolseong. However its real face has been kept in mystery. This study grafts Geophysics on modern Archaeology and approaches with scientific and systematic methods to an excavation plan or archaeological study by means of GPR exploration which can complement archaeological curiosity without destroying Wolseong fortress. The exploration area is $12,000m^2$ in front of Seokbinggo(stone storage for ice). It is only $10\%$ area of Wolseong fortress. As a conclusion, GPR detected 7 of squared buildings($8{\times}8m^2$ size), stone wall, an entrance for the fortress, lots of foundation stones, road(presumptive), and a presumptive pond which size is 35${\~}$40m in diameter.

The Wolseong Wooden moat is a unique example. Which is a vertical wall made of wood. It shows a changing point how to make the wall by digging a hole and stacking stones vertically. This study tried to to make a assumption about the construction process of the wooden structure found in the Wolseong pit moat. I sorted out wooden elements and then analyzing these features and compared with the results of the excavation. After I made 3D modelling in the order to it was made. This moat is not only a function of digging up the ground to trap water, but also a technique of building structures to maintain walls. It is a valuable material that can show the woodworking engineering techniques of the Silla Dynasty.

In order to investigate the distribution of dominant phytoplankton species in the coastal waters of Gori, Wolseong, Uljin and Younggwang, the standing crops of dominant species were studied during 1992-1996 and the relationships between standing crops and environmental variables were analyzed.The standing crops of diatom Skeletonema costatum, Thalassiosira decipiens, Chaetoceros debilis, Pseudo-nitzchia seriata, Paralia sulcata and dinoflgaellate Prorocentrum triestinum were on average from 16,373 to 118,549 cellso$l^{-1}$, from 11,180 to 210,313 cellso$l^{-1}$, from 23,341 to 55,889 cellso$l^{-1}$, from 6,784 to 15,766 cellso$l^{-1}$, from 342 to 41,596 cellso$l^{-1}$ and from 4,828 to 22,397 cellso$l^{-1}$ in the four study areas, respectively. The standing crops of Skeletonema costatum, Thalassiosira decipiens and Paralia sulcata were higher in Younggwang, while Chaetoceros debilis, Pseudo-nitzschia seriata and Prorocentrum triestinum were higher in Wolseong than other areas. The standing crops of silicoflgaellate Distephanus speculum were from 157 to 4,239 cellso$l^{-1}$ in the four study areas, showing an tendency increasing in Uljin. The abundance rates of Skeletonema costatum, Thalassiosira decipiens and Chaetoceros debilis were from 7.04 to 15.74%, from 6.95 to 33.69% and from 5.17 to 13.88% in the four study areas, respectivelyThe results of correlation coefficient between standing crops of dominant species and environmental variables show that phosphates were related with the distribution of dominant species in Gori, Uljin and Younggwang, while nitrogen compounds affected the distribution of dominant species in Wolseong. In addition, salinity and temperature affected the distribution of dominant species in Wolseong and Younggwang, respectively.

Our country traditionally employed a defensive system against the aggression by foreign powers by using a town castle and mountain castle. The moat was one of such a defensive system; however, there is few research work on a moat in comparison with its long history. This study was carried out to see the process of the changes of the Wolseong Fortress at Gyuongju, focused on the moat of the scale and nature of the construction methods to analyze such a Wolseong Fortress at Gyuongju as a result of consideration through bibliographical study, on-site investigation, and interviews, etc. This research discovered some facts as follows: the moats of Wolseong fortress at Gyeongju are roughly divided into three types; the first one is a natural moat flowing curved by the south side of Wolseong using the natural stream[Namcheon]as it is; the second one is a pond-type moat made by digging up plane non-rectangular pond along stereobate of castle wall with lakefront built with stream pebbles, and the last one is masonry moat at the east side of Wolseong with chisel-trimmed granites orderly piled in a plane triangular form. Among these, the pond-type moat was identified at the east-north-west side of Wolseong and the pond slopes from east to west as a separate one constructed with the terraces.

Various types of wooden relics are being unearthed following the full-scale excavation in Wolseong palace site, Gyeongju in Korea. In particular, a large number of relics were found in the moat surrounding the Wolseong Fortress. This study attempted to secure basic data on the shields of the Silla era through species identification, radiocarbon dating, and shape analysis of the two wooden shields excavated from the Wolseong moat. As a result of the radiocarbon dating, it was confirmed that the shields were made of wood procured in the period between the mid-4th century and the early 5th century. The species identification confirmed that the body of the relic was made with Pinus soft pine group and the handle with Zelkova serrata. It was also confirmed that the excavated wooden shield was made by first marking a thin line on a flat grain board, then marking double concentric circles and perforating small holes. The distance between the division lines is constant at about 6cm, and spaces between them are colored in red and black. The shape analysis estimated that two artifacts were more than 50cm and 36cm in width, respectively.

A well-maintained landscape can increase the competitiveness of a city. Gyeongju which is the famous ancient capital of Korea, has numerous historical resources. However, the disharmony between the historical landscape and the surrounding landscape weakens the competitiveness of the city. At present, most landscape analysis methods mainly focus on plans, photos, and animation, which have certain limitations in the expression of landscape spatial scale and materials. This study aimed to use the virtual walkthrough method to take the Wolseong District of Gyeongju historical areas as the object in order to evaluate the landscape visually. Compared with planar landscape analysis methods, such as photos and videos, the virtual walkthrough method is more immersive and intuitive to experience the spatial scale. The study results revealed images, visual characteristics, and visual influence factors of the landscape, which provide essential data for the construction and improvement of landscapes in similar historical areas in the future.

Gyeongju, Silla capital, hasn't paid much attention to a value of fortress as advanced frame of landscape all the while. All have done until now were maintaining lots of fortress including Gyeongju and setting night landscape lighting for them or building a trail in mountain fortress. Hereupon, this study tried to take a look at historical and scenic value of fortress, landscape frame of Gyeongju-Silla capital, based on Wolseong and Myeonghwalseong and find the way to contribute to it on landscape architectural level. As Wolseong(月城) and Myeonghwalseong(明活城) functioned as royal palace in Silla Dynasty, they need some research and study on fortress inside in detail rather than restoring them by simply maintaining the shapes. While Wolseong has overall excavation investigation going on, Myeonghwalseong representing mountain fortress area is losing its value due to unbefitting management to a title of world heritage. If conducting close research and study on these remains, it seems like it could contribute a lot to landscape architectural research of Silla royal palace through tracks, which will be used as royal palace. Here I suggest research direction on landscape architectural level about fortress remains in Gyeongju area as followings. Firstly, away from all research focusing on fortress shape, consecration way, etc, we need to conduct a research comprisable of inner space of fortress. As Wolseong and Myeonghwalseong functioned as royal palace in Silla Dynasty, it'll be possible to research about ponds, Nu-Jeong(樓亭), drainage facilities, oddly shaped stones, moundings, pavements, circulation systems, planting traces, etc. For this, we need to research and study through comparison with cases of China, Japan and Goguryeo of the same age. Secondly, applying garden archaeological way is possible to translate objectively regarding research of ancient garden with low literature record. But attainable achievement and information will be limited if implementing excavation based on archaeology as excavations so far regarding excavation investigation of Wolseong. The alternative to such problem is participation plan of landscaping field through the foundation of garden archaeology. We might be able to attain many results on landscape architectural level from research, if conducting research and study about Silla capital including Wolseong by applying garden archaeology such as collection of environmental sample and discovery and analysis of remains through aerial photograph, archaeological research, analysis of historical building, surface exploration, excavation technique, analysis of soil and flowerpot, etc. For this, many people majored in landscape architecture need to try and acquire archaeological knowledge. Also, we need to call attention to internal garden archaeology through international academic symposium by inviting global experts in garden archaeology field. I've suggested the study of location of Wolseong and Silla fortress in Gyeongju area, plan research on using and treating trees about the space in and out of fortress and landscape architectural research direction of Wolseong fortress.

In order to investigate the ecological characteristics of phytoplankton communities around a nuclear power plant in Gori coastal waters of the South East Sea, Wolseong and Uljin coastal waters of the East Sea and Younggwang coastal waters of the Yellow Sea, the standing crops and chlorophyll-$\alpha$ concentrations of phytoplankton were studied during 1992~1996 and the relationships between standing crops and environmental variables were analyzed. The concentrations of nitrogenous nutrients were on average 0.101, 0.094, 0.072 and 0.108mg/$\ell$ and those of phosphorus were on average 0.007, 0.008, 0.006 and 0.009mg/$\ell$ in Gori, Wolseong, Uljin and Younggwang, respectively. The N:P ratios were highly variable, ranging from 3.2 to 57.3, from 3.1 to 109.0, from 2.6 to 102.0 and from 1.0 to 165.0 in Gori, Wolseong, Uljin and Younggwang, respectively. The concentrations of suspended solids were on average 18.7, 16.7, 11.6 and 52.7mg/$\ell$ and transparencies were on average 3.8, 5.4, 7.9 and 0.7 m in Gori, Wolseong, Uljin and Younggwang, respectively. Total standing crops of phytoplankton averaged 710,659, 687,508, 656,245 and 1,278,173cells/$\ell$ in Gori, Wolseong, Uljin and Yaunggwang, respectively. The standing crops of microplankton(>20${\mu}{\textrm}{m}$) averaged 357,546, 333,638, 276,407 and 592,975cells/$\ell$ those of nanoplankton(<20${\mu}{\textrm}{m}$) averaged 353,113, 353,870, 379,838 and 574,563cells/$\ell$ in Gori, Wolseong, Uljin and Younggwang, respectively. While standing crops of diatoms were averaged 282,009, 284,710, 238,758 and 574,563 cells/$\ell$, those of dinoflagellates were averaged 46,079, 35,401, 32,906 and 16,749 cells/$\ell$ in Gori, Wolseong, Uljin and Younggwang, respectively. The seasonal standing crops of diatoms in Gori, Wolseong and Uljin were higher in Spring than other seasons, but were lower in Summer than other seasons in Younggwang. The seasonal standing crops of dinoflagellates in Gori and Younggwang were higher in Summer than other seasons, but were higher in Autumn than other seasons in U]jin. Average of chlorophyll-$\alpha$ concentrations ranged from 2.16 to 4.28$\mu\textrm{g}$/$\ell$ in 4 study areas with the highest concentration occurred in Younggwang. Indices of species diversity ranged from 2.11 to 2.24 in 4 study areas. While community structures of phytoplankton were unstable during winter and stable during summer in Gori, Wolseong and Uljln coastal waters, those of phytoplankton were stable during winter and summer than during spring and autumn in Yaunggwang. The analysis results of Pearson product moment correlation coefficient between standing crops and environmental variables showed that distributions of standing crops were affected by transparencies, suspended solids, and some nutrient(N $O_3$$^{[-10]}$ -N, P $O_4$$^{3-}$-P), even though the degree of influences were a little different according to the season and the surveyed zone.

This study is intended to clarify the structure and seasonal dynamics of warm tolerant benthic marine algal community in Korea. The species composition and biomass of marine algae at the discharge canal of Wolseong nuclear power plant on the East Coast of Korea were investigated seasonally from February 2001 to October 2005. As a result, 43 species (6 blue-green, 8 green, 9 brown and 20 red algae) of marine algae were found at the discharge canal during the past five years. In general, the number of species observed was abundant during winter to summer and less in autumn. Lyngbya confervoides and Enteromorpha compressa always occurred at the discharge canal during the past five years, and Oscillatoria brevis, Padina arborescens and Caulacanthus ustulatus were common species found more than 80% frequency during the study period. Seasonal fluctuations of mean biomass were 2-659 g dry wt m–2 and dominant species in biomass were Caulacanthus ustulatus (contribution to a total biomass proportion 37%), Enteromorpha compressa (26%) and Padina arborescens (24%). Results showed that, in the floristic composition, the green algae occurred as common algal group at the discharge canal of Wolseong nuclear power plant. In the quantitative aspect, however, the red algae such as Caulacanthus ustulatus and Ahnfeltiopsis flabelliformis appeared as predominant group at the discharge canal, in contrast to Kori nuclear power plant where there was a definite green algal dominance. Differences in algal communities developed at the discharge canals of three nuclear power plants on the East Coast of Korea can probably be related to local environmental factors.

This study examines visitors' image and behavior characteristics of Wolseong palace in Gyeongju. This area has been a royal palace during Silla periods. So many scholars dedicate to the protection of this historical-cultural heritage. The research process consists of two main steps, such as on-site field investigation and survey research. The data were collected in summer and autumn. Collected data is classified into three groups to describe visitors' behavior, time, space, and then processed by statistical methods. The results are as follows: First, there is a shortage of programs and facilities. The result shows most visitors consider Wolseong palace as a pathway for walking. Hence better functions should be developed to attract more visitors but with least effect to historical remains. The founding is that increasing programs for history exploration, enhancing lighting installation, facilities, plant arrangement, road condition and so forth would be suggested.
